PLANE.

Specification of Letters Patent.

Patented Dec. 13, 19.21.

Application filed May 3, 1921. Serial No. 466,443.

To all whom it may concern:

Be it known that I, EUGENE J. SWEENEY, a citizen of the United States, and a resident of Rockford, in the county of VVinnebago and State of Illinois, have invented a new and Improved Plane, of which the following is a full, clear, and exact description.

This invention relates to improvements in planes, an object of the invention being to provide a plane embodying certain structural features which tend vto add strength and to decrease the cost of manufacture.

A further object is to provide a novel and practical form of adjusting means for the bit of the plane which will serve to regulate the depth of cutting of the Plane and to adjust the bit for wear.

Another object is to provide a plane which will be simple and practical in construction, durable and eflicient in use, and readily adjustable.

With these and other objects in view, the invention consists of certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view mainly in longitudinal section through my improved plane on the line 1-1 of Fig. 2;

Fig. 2 is a top plan view of the plane; and

Fig. 3 is an end view of Fig. 2.

Referring in detail to the drawings, 1 represents the stock of the plane which is of the usual channel shape. The customary handle member 2 and knob 3 are provided at opposite ends of the stock. Contrary to the usual custom, a frog 4 is cast into the stock adjacent the throat thereof. By making the frog an integral part of the stock, the strength of the plane is increased and its cost of manufacture lessened. The upper face of the stock includes a pair of transverse ribs such as 5. l

A bit supporting bed 6 of any suitable hard wood is supported upon the frog 4 and is provided n its under face with grooves 7 receiving the ribs 5 and holding the bed against sliding movement on the frog. Adjacent its center, the bed is formed with a relatively wide opening such as 8. A bit 9 is slidable upon the bed and is provided with a Series of openings such as 10 adjacent its intermediate portion. A wooden shaving breaker 11 is located a ainst the face of the bit 9 and is provide with an opening 12 adapted to selectively register with any of the openings 10. The bed plate 6 cushions the bit and maintains the same in spaced relationship to the frog.

Adjacent its intermediate portion, the opposite sides of the stock are formed with integral extensions 13 and an integral cross bar 14 is carried by the extensions 13. This cross bar is located in parallelism with the shaving breaker 11 and spaced slightly thereabove. An internally threaded block 15 is supported upon the cross bar 14. Any approved means of attaching the block to the cross bar may be used such as the threaded post 16 on the block which fits a threaded opening in the cross bar. A hollow screw 17 extends through the internally threaded block 15 and a bolt 18 ts the bore of the hollow screw 17 and is retained in place by a nut 19. This bolt at its lower end is provided with an integral extension 20 having a transversely extending screw threaded bore which receives an adjusting screw 21. The end of the adjusting screw passes through the opening 12, selectivel through one of the openings 10 and extends into the relatively large opening 8 in the bed 6. It will thus be seen that after the screw 21 has been adjusted to clamp the bit and the shaving breaker against independent movement, the cutting edge of the bit may be adjusted by turning the screw 17. A cross bar 22 extending across the lower face of the shaving breaker 11 is channeled on its under face and in this channel a clamping bar 23 is located. A set screw 24 passed throu h the cross bar 22 may be used to actuate t e clamping bar 23 and clamp the shaving breaker 11 tightly against the bit 9.

It will be noted that the slot or opening 8 in the bed 6 ermits some adjusting of the bit 9. When t e lower wall yof this opening prevents further movement of the screw 21, the screw may be inserted in another of the holes 10 and adjusted in the manner above described.

Although I have illustrated one of the preferred embodiments of my invention, it will be apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention and hence I do not wish to limit myself to the precise details set forth, but shall consider myself Vat liberty to make such slight changes and alterations as fairly :tall within the spirit and scope of the appended claims. I claim: v Y l. In a plane, a stock, a frog, 'a bit, a cushioning bed plate interposed between the frog and bit spacing the bit from the frog and supported on the frog, and means preventing sliding movement of the bedV plate on the frog. Y x

2. A plane, including a stock, a frog integral with the stock and including. a transversely ribbed face, a non-metallic bed plate interposed between the frog and bit, cushioning the bit and having transverse grooves therein receiving the ribs.

3. A plane, including a stock, a frog` integral With'the stock, a bit, a cushioning bed plate interposed between the frog and bit and supporting the bit, said bed platev having an opening therein, said bit having a with the opening in the bed plate and se? y lectively with one of the openings in the bit, a screw passed through said reoistering openings in the shaving breaker and bit and extending intor the opening in the bed plate, means :tor adjusting the bit, .andsaid adjusting means being limited by the engagement of the screw With thewalls of Vthe opening in the bed plate.` Y

l. In a plane, Va stock, ya frog integralV therewith, a bit, a cushioningbedplate-in terposed between the-frog andfbit, achanneled cross bar carried bythe stock, a clamping bar in the channel, and means'for actu#V ating the Vclamping bar to hold the Ybit tightly against its supporting means.
